This is a recipe for cornish pasties for 4 people.

Sergeu [11.5K]

Answer:

I attached the completed table below.

Step-by-step explanation:

In the second column, you see that the number of people is 3 times as much as the number of people in the first column, so you can multiply all the ingredient amounts by 3.

In the third column, you see that there is twice as much beef as in the original recipe, so that means there will be twice as many people and twice as much for all the ingredients.
